The KERDI-DRAIN grate assembly consists of a frame, which can be seamlessly adjusted to the thickness and layout of the ceramic tile or stone covering via the height adjustment collar and lateral adjustment ring and grates or cleanout covers that are placed within the frame. The 4" (100 mm) standard grate assembly frame features an approximately 1/8" (3 mm) wide reveal after installation and grate/frame combinations are available in stainless steel in CLASSIC design or anodized aluminum in CONTOUR design, both available in a variety of finishes. The 4" (100 mm) KERDI-DRAIN-STYLE grate assembly frame features a minimal reveal after installation. It is made of brushed stainless steel and can be combined with one of three grate design options: FLORAL (E), CURVE (F), or PURE (G). Various metallic and color-coated finishes are available. The 4" (100 mm) TILE grate is a square stainless steel plate with KERDI laminated on the surface to allow for bonding of ceramic or stone tile, which creates a virtually invisible drainage line. The 6" (150 mm) square and round stainless steel grate assembly frames feature an approximately 3/16" (5 mm) wide reveal after installation and can be combined with stainless steel grates in CLASSIC design or a square cleanout cover. Please note that 6" (150 mm) grate assemblies and grate assemblies used with the 5 -1/4" (133.4 mm) adaptor kits only allow vertical and tilt adjustment (no lateral adjustment).
